NEEWER 82mm Center Field Split Diopter Effect Filter, Camera Linear Prism K9 Optical Glass Filter with Aluminium Frame, Blurred Refraction Foreground Repeated Color Effect Camera Lens Accessories

This is a fun inexpensive lens filter to play around with. It can be a little tricky depending on the angle of view and the light, sometimes producing bands of light that I didn't want in the photo.I'm posting a test shot I liked, of a sign on a wall with the center (clear) part of the filter turned to run from upper left to lower right.I'm looking forward to livening up my photos with this special effect filter. It's an inexpensive item that I think will help me get out of a stretch of the blahs as to my photography hobby.

I'm in love with this filter. It's great for my artistic projects

Simple funky and organic looking effect for a great price. Love it!

The first one sent to me was probably a QC defect, since one of the pieces of glass chipped off the filter from tightening and handling, but Neewer customer service amazed me. I sent them pictures of the damage and they immediately sent me a replacement. I haven't shot with the replacement yet, but from looking through the glass, I can indeed tell that this is a diopter and will work just fine when put on.

can be tricky to get the right angle but fun to explore with and be creative

As always, a great product from Neewer.

Yes, this centerfield split diopter can blur the sides (or top and bottom or diagonal corners, depending on how you rotate it). Yes, it can be wonderful for creatively challenging yourself. But don't miss the basic optics like most folks seem to, or you'll miss some awesome possibilities that can make your images look very different from how we're used to seeing the world.First, a diopter is a lens (like a full circle of glass). They have them for eye exams. If it covers your whole lens, it can be used to focus on closer objects than you normally could with the lens on your camera.Second, a split diopter isn't the full circle, but half is chopped off. When your lens is only half covered with this, it can be used to focus on something far away and something close up at the same time. And you can have blur in between, from having a wide open aperture. And you should be shooting at a low aperture number with this and hopefully at least at 50 mm, or there will be a more distinct line between the diopter and non-diopter portions.Also, in setting up this kind of shot, it's easier to (probably manually) focus on the farther away thing, then move your camera backward or forward until you get the focus right on the closer object. It's not easy, and the closer object usually has to be really close. For example, I was getting in focus objects/subjects that were 5–7 feet away paired with those maybe 8–16 inches away, using an 85 mm lens.Third, we reach the centerfield split diopter. Instead of being a diopter cut in half, it's a diopter with a strip cut out from top to bottom (or side to side—it's all relative, since it's turnable when on your camera lens anyway). Can you guess what this can do?It's like having two split diopters held up to your lens with space between them. So you can focus on two close up objects, high and low or on the sides, while focusing on something farther away. Or, focus on one close thing and one far away thing, and just leave the other bit blurry. That's way easier.If you want to run before you can walk with these optical properties, maybe try a split diopter first. There are also ones you can hold in front of your lens, but you can hold ones you attach to your lens, too, so think about how you want to use if and if you want a hands-free option.This is a fun lens (filter) if you want to try different things with portraits, or if you have a very specific dual-focus shot in mind. If this is what you're into, give it a go. It's definitely not one I'd use all the time, but I really like playing with it and thinking about what shots I can do, and it's got me thinking about this when I'm shooting and when I'm not. If that sounds like fun to you, this might be your cup of tea.See my sample pics for examples both of the standard blurriness and of the dual focus.

Didn’t get a good result with this split filter. Tried several things, photos just not coming out as expected. Loved the kaleidoscope and hole effect filters from same manufacturer. Just not this one.
